With the popularization of smart devices, large-capacity mobile power banks (power banks) have become indispensable travel companions for travelers, and power banks with a capacity of up to 20,000 mAh can undoubtedly provide longer-lasting energy protection. But does carrying such a high-capacity power bank comply with the safety regulations of the airline? Today, let's take a closer look at this issue.
According to the "Announcement on the Regulations on Civil Aviation Passengers Carrying "Power Banks" on Flights" issued by the Civil Aviation Administration, passengers can carryA power bank with a rated energy of up to 100wh (watt-hours) is on board；If the rated energy is between 100Wh and 160Wh, it must be approved by the airline before it can be carried; It is strictly forbidden to carry the rated energy over 160Wh.
It should be noted thatThe restriction on carrying a power bank is its rated energy, not its capacity。The rated energy is calculated by the capacity (mAh, i.e., milliampere-hours) and voltage (V, i.e., volts) of the power bank. It is calculated as follows:Rated energy = (capacity 1000) * voltage
Here's an example, a 20,000mAh, 5V power bank, its rated energy of 100Wh, does not exceed the allowable range. Similarly, if the voltage of a 20,000mAh power bank is 6V, then its rated energy is 120Wh. Although this power bank is also 20,000mAh, it needs to be approved by the airline before it can be carried because its rated energy exceeds the specified 100Wh.
It should be noted thatEach passenger is limited to two power banks; Power banks of all capacities must be carried in hand baggage or carried on board; The power bank must not be used to charge during the flight。In addition,The power bank should be marked with the rated energy or the rated energy can be calculated by other parameters marked.
In summary,Most of the 20,000 mAh mobile power banks with a voltage of no higher than 5V can be carried on the plane. However, in order to be sure, please carefully check the actual specifications of the power bank before traveling, and strictly follow the latest regulations issued by the Civil Aviation Authority and various airlines to ensure that your air journey is safe and convenient.
